The said letters or numerals are cut from cardboard, sheet metal orother materials, and have adjoining light and dark squares so thatwhenthe letters or figures are interconnected to provide the board, thesame may be employed as a checker or chess playing surface.

An important object of this invention is to provide a puzzle of theforegoing character that is not only educational in its use, but

that will prove of much amusement and pleasure to either children oradults.

In the drawing wherein like reference characters indicate correspondingparts throughout both of the views:

Figure l is a plan view of a chess or checker board provided by theassembly of the playing pieces of the present puzzle, and

Figure 2 is a plan view of the puzzle pieces arranged in such a manneras to present a particular phrase or expression.

of the party attempting to assemble the puzzle.

It is obvious that I do not desire tovbe limited to the exact lettersforming the phrase illustrated in Figure 2, nor do I desire to belimited to the use of letters, as the invention can I be successfullycarried out by so constructing the puzzle piecesas to provide numeralsin place of the letters. I In view of the foregoing description whenconsidered in conjunction with theaccoming the spirit and scope of theappended p claim. v

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent is An educational puzzle of the characterdescribed comprising a plurality of separate interfitting units each inthe form of a complete letter of the alphabet, said units adapted toform a rectangular board having an unbroken surface when properlyassembled with respect to each other, each unit further having its facemarked off in squares defining a checker board when the units are inv assembled position.

In testimony whereof I afiix my signature.
